• . A rectangular plastic sheet has length 90 cm and breadth 70 cm. Find its cost at the rate of 2.5 per square centimetre.

AnswEr-:

• $\boxed{\sf{\purple{The \:cost \:of \:Rectangular \:plastic \: sheet\:= Rs.15750 }}}$

Explanation -:

Given ,

• A rectangular plastic sheet has length 90 cm .
• A rectangular plastic sheet has breadth 70 cm .
• The cost of Rectangular plastic sheet is at the rate of Rs. 2.5 per cm² .

To Find ,

• The cost of Rectangular plastic sheet .

Solution-:

$\boxed{\sf{\purple{Area\:of \:Rectangle \:= length \times breadth }}}$

Here ,

• Length of Rectangular plastic sheet -: 90 cm .
• Breadth of Rectangular plastic sheet -: 70 cm .

Now ,

$\sf{\Rightarrow{\pink{Area =90\times 70}}}$

$\sf{\Rightarrow{\pink{Area =6300 \:cm²}}}$

Therefore ,

$\boxed{\sf{\purple{Area\:of \:Rectangular \:plastic \: sheet\:= 6300 cm² }}}$

Now,

☆ The cost of Rectangular plastic sheet at the rate of Rs. 2.5 per cm² .

$\sf{\Rightarrow{\pink{The \:cost =2.5\times 6300cm²}}}$
